I have Hanon's Virtuoso Pianist, (Hinrischen Edition, Edition Peters Ltd. 1987 ,©).
Towards the end of first exercise, it says "Important: proceed chromatically through all major keys!"
I couldn't understand this. I guess I can try doing this with most keys with sharps (CGDAE) or F, but how on Earth am I supposed to follow this fingering with keys like Bb, Eb, Ab etc. which has more complicated fingering any way.
Can I get some easy to understand explanations and tips?
